6G Celicas Forums

She's still running decent. I droped the full syn and put a syn blend back in and she seems to run better. Like before the overheat. Well last overheat. The radiator cap didn't help she still leaks out of the cap but she's not losing much water over the days just burning them off.

It's fine like it ran before. But now u mention it the radiator cap is a lil hard to find the sweet spot. I was actually thinking about buying one of those 10$ caps that have a lock thing on it to help pressurize.

No codes, and she's not wanting to over heat on just water with the resivor disconnected. Could there still be a code this even tho no check engine light is on?

I messed with the idle screw ornthe air screw and it runs better now. She still wants to over heat after a hour of driving but it's cause I have water in the radiator right now to see what's going on.

But it only over heats cause the waters gone. So idk. I'm thinking about taking the thermostat out and look at it. But I just replaced it with in the last 600miles. So idk.

Well it's not the head gasket. Guess I need to look at the thermostat and idle air control valve? Isn't the idle air control valve by the idle screw and stuff like that?

Also what radiator resivor matches with the celica?

But wouldn't she not run at all with a blown head gasket? Oil or something somewere? She still runs like she used to just a rough idle when it wants to use at 700ish.

And how would I check compression by myself?

Took apart my fuel lines and my fuel rail, air filter housing, and now I'm working on getting the maf out to see if it needs cleaned.

My car overheated the other day n now she dosnt want to run under 1000rpms

Ok I have a 1994 celica ST, with 289xxx miles. Supposedly at around the early 200xxx ish miles a engine with 150k miles was swaped in. Doesn't look like it tho.
The other day I was driving home it was about 70deg outside when it's normally been under 50deg everyday here in Missouri.
And I noticed the AC wasn't blowing as cold as it does, then she started to overheat she over heated and shut down doin 50mph lost everything, breaks, steering.
Got it home it's hard to start and now won't stay running under 1000k rpms. It has a nasty idle when she wants to stay running. And idk what it could be.

I just recently changed all this with in the last 1000miles.
Radiator, thermostat, fuel filter, spark plugs, spark wires, distributor cap and distributor spark thing. New air filter, did a radiator flush with the new used radiator in it. Also did a 3 part fuel system cleaning in it .

Any idea as to why she won't stay running?


***Edit***
I'm sure my collent went out the crack I have in the resivor because there's no cracks or leaks in the radiator.

***Edit2****
Also went from a synthetic blend to a full synthetic with in 300 miles

And I'm kinda thinking it's the head gasket.
